Want to modify open PO from 8/21 and get this meesage. This transaction was on or before your company's closing date. Editing the transaction will affect your books.

Hey there, fmlonline15.

QuickBooks Online has a security feature to set a closing date. Once this option is enabled, you will see the pop-up message. This feature prevents unauthorized changes to any transaction recorded before the closing date.
